java的字典序排序

⑴ java按著字典順序排序

如果同時有 new String[] { "ye", "yel", "yellow" };你的排序是ye,yel,yellow
但是如果new String[] { "yel", "ye", "yellow" };排序就變成 排序後:yel ye yellow

⑵ Java怎麼按照漢字字典順序給字元串排序

//按照中文第一個字母升序排列的實現
import java.text.Collator;
import java.util.Arrays;
import java.util.Comparator;
public class test {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Comparator<Object> com=Collator.getInstance(java.util.Locale.CHINA);
String[] newArray={"上海","天津","廣州","杭州","遼寧","南京","武漢","北京","廈門","內蒙"};
Arrays.sort(newArray,com);
for(String i:newArray){
System.out.print(i+" ");
}
}
}
